1. A method for monitoring the functioning of an RFID-based radio communication network in a spatially extensive area, wherein a plurality of RFID tags carry out a radio communication with a reader, comprising:
- carrying out, in the area of coverage of the RFID system in which at least one fixed reference RFID tag is arranged, a periodic radio communication between the at least one fixed reference RFID tag and the reader;
sending the data from the reader to a control center;
comparing the data in the control center with previously transmitted data relating to the at least one reference RFID tag;
arranging the reference RFID tag in a marker field of a marker device that generates a spatially delimited electromagnetic field in a specific geographically delimited area of the area of coverage of the RFID system, andwherein the data stored in the control center relating to the radio communication with the reference RFID tag is field strength data indicating a field strength of the received radio communication, and the field strength data for each communication is compared with previously received field strength data.

8. An apparatus for monitoring the functioning of an RFID-based radio communication network in a spatially extensive area, comprising:
-
a reader, a control unit, a plurality of RFID tags carrying out radio communications with the reader, and at least one fixed reference RFID tag in the area of coverage of the RFID system that performs a periodic radio communication with the reader, and sends data relating to the periodic radio communication to the control center, wherein the control center compares the received data with previously transmitted data; wherein the reference RFID tag is arranged in a marker field of a marker device that generates a spatially delimited electromagnetic field in a specific geographically delimited area of the area of coverage of the RFID system, and wherein the data stored in the control center relating to the radio communication with the reference RFID tag is field strength data indicating a field strength of the received radio communication, and the field strength data for each communication is compared with previously received field strength data. - View Dependent Claims (9)
